The shape of the BEPC has been described as a tennis racquet, with a [[linac]] with a beam energy of from 1.5 to 2.8 GeV serving as the handle, injecting counter-rotating beams of particles into a [[storage ring]] at the head, giving collision energies in the range from 3.0 to 5.6 GeV. The BEPC was built to investigate [[Tau (particle)|tau]]-[[Charm (quantum number)|charm]] physics, using the Beijing Spectrometer. Major accomplishments of the original BEPC included precision measurement of the Tau mass.<ref>[https://cerncourier.com/a/future-plans-take-shape-in-beijing/ Future Plans Take Place in Beijing], Cern Courier, 30 October 2000.</ref><ref>{{cite journal | url=https://www.science.org/doi/abs/10.1126/science.262.5132.368 | doi=10.1126/science.262.5132.368 | title=The Present and Future of China's Particle Physics Research | year=1993 | last1=Zheng | first1=Zhipeng | journal=Science | volume=262 | issue=5132 | page=368 | pmid=17789941 | bibcode=1993Sci...262..368Z | url-access=subscription }}</ref><ref>{{Cite book |url=https://doi.org/10.1007/978-3-030-34245-6_10 |doi=10.1007/978-3-030-34245-6_10 |chapter=The Largest Accelerators and Colliders of Their Time |title=Particle Physics Reference Library |year=2020 |last1=Hübner |first1=K. |last2=Ivanov |first2=S. |last3=Steerenberg |first3=R. |last4=Roser |first4=T. |last5=Seeman |first5=J. |last6=Oide |first6=K. |last7=Mess |first7=Karl Hubert |last8=Schmüser |first8=Peter |last9=Bailey |first9=R. |last10=Wenninger |first10=J. |pages=585–660 |isbn=978-3-030-34244-9 |s2cid=219874352 }} See Table 10.11, Historical listing of electron-electron and electron-positron colliders</ref></div></td></tr>

The construction of the original Beijing Electron Positron Collider was approved in 1983, as China was emerging from the [[Cultural Revolution]], based on a proposal developed by [[Xie Jialin]], who went on to oversee the construction of the machine. The construction of this collider was considered so important that then vice-premier [[Deng Xiaoping]] attended the groundbreaking in 1984 and returned in 1988 as the machine neared operation.<ref>Matin Durrani, Pushing the Boundaries, [https://physicsworld.com/a/pushing-the-boundaries/ Physics World], 15 Sep 2011.</ref><ref>Min Zhang and Qian Pan, Jialin Xie wins China’s top science award, [https://newsline.linearcollider.org/2012/02/23/jialin-xie-wins-chinas-top-science-award/ International Linear Collider Newsline], 23 February 2012.</ref><ref>Deng Xiaoping, China Must Take Its Place In the Field of High Technology, Oct. 24, 1988, [https://dengxiaopingworks.wordpress.com/2013/03/18/china-must-take-its-place-in-the-field-of-high-technology/ The Selected Works of Deng Xiaoping]</ref></ins></div></td></tr>
